roadway, except as follows:

(1)
When
overtaking and passing another vehicle proceeding in the same direction, or
when making a left turn under the rules governing such movements;

(2)
When an obstruction exists making it
necessary to drive to the left of the center of the highway; provided, any
person so doing shall yield the right of way to all vehicles traveling in the

distance as to constitute an immediate hazard;

three or more marked lanes for traffic under the rules applicable thereon;

(1)
Upon
all roadways any vehicle or trackless trolley proceeding at less than the
prevailing and lawful speed of traffic at the time and place and under the
conditions then existing shall be driven in the right-hand lane then available
for traffic, and far enough to the right to allow passing by faster vehicles if
such passing is safe and reasonable, except under any of the following
circumstances:

(a)
When overtaking and
passing another vehicle or trackless trolley proceeding in the same direction ;

(c)
When the driver must
necessarily drive in a lane other than the right-hand lane to continue on the
driver's intended route.

(2)
Nothing in division (B)(1) of this
section requires a driver of a slower vehicle to compromise the driver's safety
to allow overtaking by a faster vehicle.

(C)
Upon any roadway having four or more
lanes for moving traffic and providing for two-way movement of traffic, no
vehicle or trackless trolley shall be driven to the left of the center line of
the roadway, except when authorized by official traffic control devices
designating certain lanes to the left of the center of the roadway for use by
traffic not otherwise permitted to use the lanes, or except as permitted under
division (A)(2) of this section.

This division shall not be construed as prohibiting the
crossing of the center line in making a left turn into or from an alley,
private road, or driveway.

Except as otherwise provided in this
division, whoever violates this section is guilty of a minor misdemeanor. If,
